I used the .410 for all my shooting needs for about a five year period to get past a nasty flinching problem. I had tired everything. Used middle finger as a trigger finger, pre mount gun, low gun, gas auto, different guns, hypnosis and learned how to shoot left handed. I'm would flinch one out of four shots somedays and nearly shot others. So I went to shooting a .410 for everything for three plus years. 200-500 rounds a week and gradually the flinch went away. Kept shooting the .410 for two extra years and graduated to a 28. After about a decade I can shoot anything from my mighty .410 up to a 10 ga. So sometimes a .410 can be used to fix a shooting problem.
Full disclosure. I could not hunt waterfowl with my mighty .410. I did shoot a few wild quail and more game farm birds. I shot a lot of clay targets. But the .410 is not a do all gun in my hands. Inside 25 yards I am quite good with it and can cleanly kill anything. 25-30-33 yards I can pick my shots. I do shoot a lot of dove with it and set known distance markers so when I say 33 yards I mean it and then only on calm days. Not an estimated 33 yards but a paced off distance. When you measure a 33 yard shot to the bird it becomes a 35-37 yard shot because you shoot up the long side of a triangle.
Most people think a 33 yards shot is 40 plus yards in part because we are lousy at judging distance and partly because they step it off to where the bird is retrieved. They forget to subtract the fall distance after the bird is hit.
